TL;DR: In this paper, the authors considered the effect of back-tunnelling on the amount of charge acquired by an insulator when it is contacted to a metal, and also the extent to which it can lose charge by back-tunneling during separation.
Abstract: Tunnelling of electrons between a metal and localised states in an insulator is considered, with a view to determining the charge that an insulator can acquire by this mechanism when it is contacted to a metal, and also the extent to which it can lose charge by back-tunnelling during separation. Traps at a single energy are considered primarily, but some attention is given to traps distributed over a range of energy. Back-tunnelling is likely to be significant only at the very highest observed charge densities.

TL;DR: In this article, a general description of space charge-limited photo-enhanced currents (PEC) in organic insulators is given, based on the distribution function for the occupation of traps under simultaneous thermal and optical charge detrapping.
Abstract: A general description is given of space-charge-limited photo-enhanced currents (PEC) in organic insulators. The model developed is based on the distribution function for the occupation of traps under simultaneous thermal and optical charge detrapping. The theoretical results satisfactorily reproduce all features of the experimental voltage and spectral characteristics of the PEC illustrated on anthracene and tetracene single crystals.
